GRINDING, CRUSHING, AND MIXING 'MACHINE OR MILL.

Application filed August 14, 1924, Serial No. 732,096,.and in France September 1, 1923.

This invention is directed to an improve ment in grinding nulls designed part1cularly for l'iandling more or less fine material and involving a rotating grinding member having an outer or peripheral surface or edge for grinding purposes.

Whereas heretofore grinding mills of this character have been provided with twistedarm grinding members, the peripheral or grinding edge of which was concentric to the axis, the grinding function has been unsatisfactory particularly in the handling of fluid moist or viscous materials, due to the fact that the material was continually slipping away from the grinding surface, and

hence but little real grinding action was had.

The present invention is directed to modifying the grlndmg surface so that in each instance, the surface presents an angular rela-. lion to the cooperating grmdmg surface so that the material is continually compressed and thus held for effective grinding.

The invention is illustrated in the accompanying drawings, in which:

Fig. 1 is an enlarged sectional view through the usual type of rotating element involving twisted arms.

Fig. 2 is a similar view showing the modilicd arrangement, of the grinding surface according to the present invention.

Fig. 3 is a view in elevation.

Fig. a is a view in section of the improved grinding element.

Fig. 5 is aview in elevation of a modified grinding element.

Fig. 6 is a view illustrating diagrammatically the action of the grinding element. I

Fig. 7 is a view illustrating the application of the improvement to a working apparatus.

In Figs. 3 and a, the grinding element, which it is understood cooperates with a rotating or revolving vat or pan in which the material is placed, includes a frame 1, from material tends to exert a continually increasing pressure thereon as the arms are rotated, thereby holding the material in position to be effectively acted on in the grinding operation.

In Fig. 5, there is shown a slightly modilied form, in which the revolving grinding element is in the form of a cylinder with sinuous channels 10 therein providing intervening grinding sections 11, which it will be seen from the diagrammatic illustration. in

liig. 6 is substantially the same as that described in. connection with the grinding sursame circumferential plane and curving in the axial direction, said arms having grinding surfaces operating to increasingly compress the material on the cooperating grinding surfaces in the direction of grinding.

2. A rotary element of a. grinding main the same circumferential plane and curving in the axial direction, said arms having grinding surfaces with the initial edge spaced farther from the cooperating grind-- ing element than the final edge.

3. A rotary element of a grinding machine, comprising a central disc mounted for rotary movement, and a plurality of arms extending axially therefrom in substantially the same circumferential plane and each curved in the axial direction so that the free end of one arm is in the, axial plane of the disconnected-end of the adjacent arm, the grinding surfaces of said arms being formed to gradually and increasingly compress the material on the cooperating grinding surface in the direction of grinding.

4.. A rotary grinding element of a grinding machine, including a series of arms disposed in the same circumferential plane and curving in the axial direction, each arm having a grinding surface for cooperation with a grinding surface common to all the arms,

l chine made up of a series of arms disposed the arm-grinding surface being inclined away from the common grinding surface in the direction of grinding. I

5. A rotary grinding element of a grinding machine, including a series of arms disposed in the same circumferential plane and curving in the axial direction, each arm having a grinding surface for cooperation with a grinding surface common to all the arms, a cooperating grinding surface commonto all arms, the leading edge of each 10 arm-grinding surface being spaced farther V than the trailing edge from the cooperating grinding surface. i
